The purpose of this invention is to provide a method with which it is easy to perform screening for an agent that proliferates or an agent that minimizes the reduction in MCSP-positive basal epidermal stem cells. Provided is a screening method for a laminin 511 expression promoter, which takes the expression of laminin 511 as an indicator. Also provided is an agent for improving skin barrier function, elasticity, hydration and inflammation, said agent including at least one extract selected from among a group consisting of brown algae, red algae and green algae.

An extract of Himanthalia elongata and a cosmetic composition comprising a carrier and said extract is provided. The extract and the composition show whitening and anti-ageing activities.

A method for production of red ginseng hydrolysis concentrate according to an embodiment of the present disclosure includes carrying out an enzyme reaction of red ginseng concentrate by adding an enzyme solution followed by addition of alcohol to prepare a mixture solution of red ginseng and alcohol, and centrifuging the prepared mixture solution of red ginseng and alcohol followed by concentration under reduced pressure of a supernatant separated by the centrifuge, and a red ginseng hydrolysis concentrate produced by the aforementioned process.
